In the recent discussions of this subject, I don't recall any mention
of Rx EQ settings, or FLx gain settings as ways of obtaining
more output. For CW operation, I'm using +10 dB gain in the
200 Hz and 400 Hz Rx EQ bands (my CW pitch settings
are always set between 300 and 400 Hz). I get plenty of
headphone volume in my cheap Radio Shack stereo headset
(especially if I remember to keep the earpiece
volume controls turned up!)
You really shouldn't need to increase the filter gains over what is
necessary to equalize the filters. For example, I have my 2.8 and 1 kHz
filters set to 0 db, and the 400 Hz one to +4 dB. I verified that this
was correct by using a steady signal source (an Elecraft XG-1), turning
the AGC off and using the dBv function to compare the gains.
If you need more headphone volume, first make sure that you have set the
AF Gain in the CONFIG menu to HIGH. If that doesn't work, something's wrong.
